Many people spend at least half the year awaiting the return of summer. They dream of long, hot days, and weather warm enough to allow them to finally expose their skin to the sunlight. There are some places, however, where summer is an almost perpetual state of being—where the heat can get unbearable and the sun is something to seek respite from rather than revel in. According to the Guinness Book of World Records, the hottest place in the world is Death Valley in California, where temperatures reached 134ºF/ 56.7ºC on July 10, 1913. This article takes a look at eight of the hottest cities in the world, some of which are record-holders in their own right.

According to the World Meteorological Organization, Bangkok is the hottest city on the planet - not because of any particularly impressive peak temperatures, but because it is consistently hot all year round.

It’s also one of the hottest cities in the world, with a hot, dry climate offering record highs of 120ºF/ 49ºC. Throughout April, May and June, average maximum temperatures exceed 104ºF/ 40ºC.

Ahvaz, Iran

Ahvaz, Iran

Highest Temperature Recorded: 129ºF/ 54ºC
Built on the banks of the Karun River, Ahvaz is an industrial city with average highs of around 115ºF/ 46ºC during July, its warmest month. The city’s record high is a fever-inducing 129ºF/ 54ºC, making it a contender for hottest place in the world during the summer. Frequent sand and dust storms and an absence of rain from July to September compound its sky-high temperatures. Unlike the rest of Iran, there are few reasons to visit Ahvaz, which was ranked as the world’s most air-polluted city in 2011; however, the riverbank offers a series of parks and bridges that make it both the coolest and the most scenic part of the city.

Nightfall brings little respite, with after-dark low temperatures often exceeding 86 °F/ 30°C during the summer months. Kuwait City’s record high is 126ºF/ 52ºC, while it rains on an average of just 19 days per year. Visitors shouldn’t be put off by these eye-watering statistics, however, as Kuwait City offers an intriguing blend of past and present expressed via an eclectic roster of museums, art galleries, upscale malls and traditional souqs.

Highest Temperature Recorded: 121.6ºF/ 49.8ºC

Famous as the birthplace of Muhammad, Mecca is Islam’s holiest city. It’s also another scorchingly hot destination, with around 22 rainy days per year and average annual highs of 100.5ºF/ 38ºC. The highest temperature recorded in the city is 121.6ºF/ 49.8ºC, but even in winter, average temperatures hover at a balmy 77ºF/ 25ºC. Of course, the majority of Mecca’s visitors aren’t there for the weather - instead, millions of Muslim pilgrims arrive each year to perform the Hajj. The city is home to the world’s largest mosque, Masjid al-Haram, and the Kaaba, considered the House of Allah; however, Mecca is strictly off-limits to non-Muslim visitors, although that may change in the future once Saudi Arabia starts issuing tourist visas to non-Muslims.

Although Miami has the highest mean annual temperature of any U.S. city, the Arizona capital claims the hottest average highs in summer.

Highlights of what is sometimes the hottest place in the world include the Heard Museum’s Native American artworks, and the breathtaking flora of the Desert Botanical Garden.
